I think they're building a decentralized exchange that will run in a browser... hopefully where you can list your own coins and tokens without having to pay "listing" and "maintenance fees" to exchanges.
Bitsquare is a bitcoin decentralized exchange but there is not enough traders using or showing interest in the platform. If that is what they are working on then it will be another disappointing outcome once again.
Another decentralized exchange is set up with no users.
